teko Astra-517 Operating Manual

The present Operating Manual is intended to provide a guid-
ance on operating principles, correct use, storage and mainte-
nance for the PIR detector "Astra-517" (hereinafter-detector)
(Figure1).
The manufacturer reserves the right to make improvements in
the design of the detector without prior notice. The alternations
shall be included into a new edition of the Operating Manual.
1 Application
1.1 The detector is purposed to detect in-
trusion into a protected area indoors and to
generate an alarm notification by opening
of the signal relay output contacts.
1.2 The detector is powered from any DC
power supply with nominal voltage of
12V and maximum pulsation amplitude
0,1V.
2 Principle of Operation
2.1 The operating principle
is based on registration of
changes occurring in ther-
mal flux, when a person
crosses a detection zone,
consisting of sensitive
zones. Each sensitive zone
consists of two elementary
sensitive zones (Figure 2).
The sensitive zones of the
detector are formed by a
Fresnel lens and a bi-areal
pyroelectric sensor.
Electric signals from the
pyroelectric sensor shall be
sent to a microcontroller,
which generates alarm no-
tification in accordance
with a preset operation al-
gorithm by opening of op-
toelectronic relay circuit.
2.2 The sizes of detection
zone may be varied due to
the position of the printed circuit board of the detector. With in-
trusion detection range of 8 m, density of the sensitive areas
will be increased.

5 Structure
5.1 The detector is a unit consisting of a base and a detacha-
ble cover. A printed circuit board with radio elements and a
block of screw terminals for external connections is installed
inside the unit. (Figure 3).
5.2 The PC board shall be secured in the position to enable the
desired detection range (8m, 12m) of the detector with a
screw.
5.3 The PC board includes an indicator, which controls operation
of the detector.
5.4 The cover on the inside is provided with a lock pin holding
down and securing the lens.
5.5 The pyroelectric sensor is equipped with a cap provided
with a reflector making a near detection area.
WARNING!
It is prohibited to operate the detector without the
cap.
5.6 The detector can be mounted either directly on the wall or
in a room corner, or it can be mounted using brackets (includ-
ed in the scope of delivery).
